Two primary school children aged between four and five scaled a 6 ft high fence in a bid to escape school and walk home.
The runaway reception students at Thirsk Community Primary school in Yorkshire climbed a fence on the far corner of the school field and attempted to walk home to a nearby area called Norby.
After a thorough search of the area the students were located by school staff.
It is believed the students crossed a busy road in order to reach their grandmother's house in Norby where they were found on Friday afternoon.
In a message sent to parents by head teacher Richard Chandler he said the incident occurred during lunchtime.
He wrote: “As the class lined up to go back into the school the two boys were not accounted for. An immediate search of the school and grounds was made and then the parents were called.
“The two boys were quickly located. They had arrived at their grandmother’s house about a mile away. They were collected from there by staff and parents.”
He said the school had launched an investigation into the incident which was being led by the County Council’s School’s Health and Safety team.
The school has implemented a number of safety precautions to ensure the safety of its students.
“Supervisory arrangements throughout the day have been reviewed, all children have been spoken to about the importance of staying safe. For the current time Reception children are to play during break-times in their own enclosed area,” Mr Chandler said.
He continued: "The school takes its responsibilities for pupil safety very seriously."
